Benefits of technology
The present invention is about a way to repair damaged pipes or conduits by applying a repair material to the inside wall surface using a flexible bladder with heating components. The repair can be done in a portable container and the bladder can be expanded to press against the pipe wall surface. The invention has the advantage of being able to repair pipes quickly and easily without the need for major construction or shutdowns.
Problems solved by technology
The cause of leakage can vary from improper installation to environmental conditions to normal aging or the detrimental effects of the substances transported on the pipe materials.
Regardless of the cause, leakage is undesirable.
This is not often possible.
This has resulted in many failures due to premature curing of the resin, inadequate resin cross-linking and shrinkage.
In addition, because the resin is applied to the repair material at the installation site (and typically in uncontrolled conditions), inconsistencies in resin content or mixing procedures, inadequate resin distribution within the repair material, and premature resin curing can be expected.
The shortcomings of these types of systems lay in the difficulty of the prescribed radiant light source to penetrate through the thickness of the repair material and the overall fragility of such devices.
